John Scott Harrison (October 4, 1804 – May 25, 1878) was a member of the United States House of Representatives from Ohio and the only person to be both the child and the parent of U.S. Presidents. His father, William Henry Harrison was the ninth President in 1841; and, his son, Benjamin Harrison, was the 23rd President from 1889 to 1893. Harrison did not live to see his son become President, and his father did not live to see John Harrison become a member of Congress.

In 1824 he married Lucretia Knapp Johnson (16 September 1804 – 6 February 1830). They had three children; Elizabeth Short Harrison (1825–1904), William Henry Harrison (1827–1829) and Sarah Lucretia Harrison (1829-1917).

On 12 August 1831 in Cincinnati, Ohio, he married Elizabeth Ramsey Irwin (18 July 1810 – 15 August 1850). He and Elizabeth had 10 children;

He was elected a Whig to the U.S. House of Representatives in 1852, reelected an Oppositionist in 1854 and served from 1853 to 1857. After being defeated for a third term in 1856, Harrison retired to his estate "Point Farm" in North Bend, Ohio where he died on May 25, 1878. He was interred in the William Henry Harrison Tomb State Memorial in North Bend with his parents and other family members. Harrison's body was stolen by grave robbers until it was eventually returned to its final place of rest.

At that time it was common practice for graves to be robbed for recently deceased bodies for use in teaching dissection and anatomy at medical colleges. As a result, many precautions were taken to secure Harrison’s grave, including building a cemented brick vault, filling the grave with earth mixed with heavy stones, and employing a watchman to check the grave each hour of every night for a week.

The day of Harrison’s funeral it was discovered that the body of young Augustus Devin, which had been buried the previous week in an adjoining grave, had been stolen. The following day, one of John Harrison’s sons, together with a friend of Devin, traveled to Cincinnati to look for his body. With search warrants in hand they went to the Ohio Medical College, where they discovered not Devin’s body but the naked body of John Scott Harrison hanging from a rope down a chute beneath a trap door. Devin's body was later found preserved in a vat of brine at the medical college of the University of Michigan.[1]
